Too bad Barry died, though. That sucks, he was a good character.
Is Havok dead? Probably not. Mustang got pretty messed up, but he killed Lust in the process. The funniest part was when Lust started jiggling her boobs in front of Havok and then Mustang says "You've always had a thing for big boobs." Classic.
It was interesting that a philosopher's stone is at the heart of Lust. I wouldn't be surprised if she came back. She's not dead. Maybe this body is, but not her character.
2014 is going to be a good year. More content, more streamlining. Be a part of history!
